Car Alarms: security issue, alarmtek, dash area

Question
2007 pathfinder alarm goes off by itself armed or disarmed factory system when it happens unable to cancel but when it works all systems operate correctly. no set pattern vehicle starts when alarm is going off

Answer
Please be more descriptive if possible.

"GOES OFF?"

I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.

Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
(doubtfull since none of the notes show this
car as having a factory alarm system)=FACTORY

Or,

is it: flashing parking lights,
an LED in the dash area, and a siren
going off?= AFTER MARKET

Let me know more on this to better
advise you on a course of action
to take.
